SPECIFICATION forming part of Letters Patent No. 528,063, dated October 23, 1894. Application'filed March 13, 1894. Serial No. 503,506. (No model.) Patentedin England November 17, 1892, No.20,802.

To all whom it may concern.-

Be it known that we, HENRY HERBERT AN- DREW and ALFRED ROWE BELLAMY, subjects of the Queen of Great Britain, and residents of Reddish, in the county of Chester, England, have invented certain'Attachments for Gas- Engines and the Like, (for which we have obtained Letters Patent in Great Britain November 17, 1892, N 0. 20,802,) of which the following is a specification.

Our invention is designed to prevent the bursting of the water jacket of the gas engine due to freezing.

In the drawings Figure 1, is a sectional view oi one form of the invention and Fig. 2, a similar View of another form in which an automatic cut off valve is employed. I

In order to prevent the cylinder 12 of a gas or similar engine from being burst through freezing of the water in the cylinder jacket we pro pose to place outside (or in a position most exposed to the weather) and in connection with the water jacket I) of the cylinder, a chamber or box cl fitted with a spring covering a which would yield or with a thin and weak cover which would break under sudden pressure. A tap f to cut off the supply of water from the reservoir 9 to the jacket I) would be kept closed at night, or when the engine was not working, to prevent any essential escape of water, in case the cover eon the chamber at should be broken by frost and a suitable provision is made in the chamber or box to drain the water from the jacket of the water supply reservoir is shut ofi? and the water from the jacket b drains off through the pipe Z.

We claim as our invention- 1. In combination with a water jacket of a gas engine, the outlet pipe leading therefrom, the box 0? connected withtsa'id pipe and having an open side, and the relief cap e closing said open side, substantially as described.

2. In combination with the relief box d and cover 6 the lovers and rods h, 2', j operating upon the valve spindle and valve is, f, in such a manner as to shut oft communication with the water reservoir and drain the water from the cylinderfjacket onthe freezing of the contents of the box (1' and consequent movementof the cover 6, as hereinbefore described and shown.

In witness whereof we have hereunto set our hands in presence of two witnesses.
